WI W neshpplicat'ion filed July 25,

To all whom it may concern:

Be it known that I, AUoUsr A. GASSINGER, citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improven'ients in i l indow Screens, of which the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to new and useful improvements in screens and more particularly to a window screen of the roller type wherein the screening. is wound upon a spring controlled roller.

The primary object of the invention is the provision of such a screen which is adapted for use in connection with windows of various heights and widths, the roller upon which the screening is wound being adjustable as to length and the spring thereof being so constructed and connected as to nor mally hold the screening wound upon the roller and being placed under tension when the screening unwound.

A further objeot consists in the provision of novel means for engaging a transversely disposed bar carried bythe screening for holding said screening, unwound from the roller, over the window opening, and novel means for engaging the longitudinal vertical edges of thescreening to provide against the displacement of the screening and to prevent openings through which flies or other insects might pass. i

It is, a still further objectto provide a shield, either carried by the screen or by the window sash, to prevent flies, or other insects from enteringbetween the screen and window sash, the shield, it carried by the screen, engaging the sash to close openings and it' carried by thesash engaging the face of the screen fol-tho same purpose.

l Vith the above and other objeets in view, which will appear the description proceeds, my invention consists of the novel details of construction and arrangement of parts described in the-following specification and illustrated in'tlie accompanying drawings, andvwhile I have illustrated and described the preferred embodiments otthe invention it will be understood that such changes may be inadeas will follow within the scope of the appended claims.

ln the drawings 1 indicatesthe window frame and 2 the'lwindo w sash, each of oidinaryandany well known construction, and A andB are vert cal extend ng side rails going forward to make up theframe of my screen,

each of the said-side rails; being of angle iron construction forming the right angle extending arms 8 .a1 1dfl, the,.arms 3 adapted to engage the'sides of the window frameand the armsc extending a short distance over the window openings, as clearly shown in the drawing "lhe side rails are secured tothewindow. frame by means oftlie screws 0 or other su t-able fasteners which pass through openings formed in the arms 3 and engage in the "frame. The outer edges of the armsS, ot.the.side rails, preferably extend a short. distance beyond the face of the window frame for a purpose which will later 31 1 9-3 i :rrroller 6 is, }arried by, and maintained between theside railsA and B, adjacent. the upper ends, said roller provided in one end with a longitudinal extending recess 7 which is adaptedto receive a rotatable spindle 8, the outer end of which is elongated, as shown at 9 tobe received.in an elongated opening tormed'in, the arm 3 of the side rail A. A coilspring 10 is received in the recess 7, and

surrounds thespindle 8, one end of said coil spring being connected tothe spindle at 11 Ill) and the opposite end being connected to a bar 12, or other suitable projection, secured in the recess 7. The opposite end of the roller receives a screw threaded spindle 13, the outer end of which is reduced and round, as shown at 14, said reduced round end 14;

adapted to be received in a round openingformed in the arm 3 of the side rail B. The spindle 18, adjacent the outer end, is provided with a square shoulder 15 adapted to be en 'aged by a wrench or similar instrument for adjusting tie spindle with respect to the end of the roller, said adjustment adapt ing the roller to be used with windows of va rious widths. Screening it; is secured to and adapted to be wound upon the roller 6, the screening being of any desired type although I preferably use a cloth fabric as this will more readily wind upon the roller than will the wire screening. To the outer edge of the screening I attach a transversely disposed har 17, said bar being preferably con structed of metal adapted to be bent into U-shaped form to engage over the edge of the screening and secured thereto by the prongs 18, struck from one arm of the shield, and which pass through the screening and engage througl'i openings formed in the 0pposite arm. A finger piece 19 is struck from the bar and extends at right angles thereto so that it may be easily grasped for operating the screen.

To each of the side rails A and B I hingedly connect plates 20, preferably by means of coiled springs 21, one end of the springs being connected to the arm 3 of the rail at 22 and the opposite end being connected to the plate 20 at 23, I use a plurality of these coil springs 21, vertically spaced, so as to normally hold the plates 20 against the face of the arm 4 of the side rail. At the lower end the plates 20 are provided with an off set position 24; forming a recess for the reception of the transversely extending bar 17, of the screening, when the said screening is unwound from the roller and covers the window opening. It will be understood that when the screening is unwound the longitudinal vertical edges thereof will engage over the faces of the arms 4 of the side rails A and B and be tightly held there against by the spring pressed plates 20. lVhen the screening is to be wound or unwound it will be necessary that the plates 20 be raised from engagement with the arms of the side rails and in order to hold the said plates raised, against the tension of the springs 21, I provide the catches 26 which are pivotally connected to the plates 20 at 26, the outer ends of the catches being of U- shaped construction so as to engage over the edges of the arms 3 of the side rails.

Inorder to prevent flies,-or other insects, from entering between the screen and window sash I secure bar 27 transversely across the sash in position to engage the face of the screen.

In F1 6 I have shown a slightly modified form or spring for connecting the plate 20 to the side rail. In this form of the 1nvention instead of using the coil sprlngs 2.1 I use the flat springs 28 which are of right angle construction and adapted to be secured to the arm 3 of the side rail and to the plate 20 by means of the rivets 29 or other suitable fastening means.

In Fig. 10 I have shown a slightly modified form of shield or guard for preventing insects from passing between the screen and sash. In this modified form the shield or guard is in the form of a curved plate 30 adapted to extend over the top of the roller (5, between the side rails A and B and is )rovided with an extension 51 extending downwardly at an angle to engage the face of the window sash. As e early shown in the drawings, this shield or guard 30 will merely be hung over the roller, in engagement with the window sash, by the extension 81, so as to engage the upper edges of the arms 3 of the side rails.

From the above detail description it is thought that the construction as well as the manner of using my screen will be clearly understood. It will be seen that in reality the screen frame is merely composed of the side rails A and B and by this construction the screen is adapted to windows of various widths and the spring controlled roller may be adjusted by the adjustable screw thread spindle 13, to adapt itself to various sizes of Windows. In order to adjust the roller the square shoulder 15 on the spindle 13 may be engaged by any suitable form of wrench or other implement. The spring roller 6 is so constructed as to normally hold the screening 16 wound thereon and when the screening is unwound the spring will be placed under tension. Tire plates 20 will be normally held in engagement with the arms 4. of the side rail by the springs and when it is desired to unwind the screen to cover the window openings, the said plates will be raised to extend parallel with the of the side rails. The plates are arms 0 held in this raised position by the catches 26whieh, as described, engage the outer edges of the arms 3. When the screening has been unwound to cover the opening the catches 26 are disengaged from the arms 3 and the springs will force the plates 20 back into original position to securely hold the longitudinal vertical edges of the screening between the arms a of the side rails and the plates 20. WVhen the screen is in lowered position the transversely disposed bar 17 will be received in the off set portions of the plates 20, said off set portions engaging the bar to prevent the spring controlled roller from overcoming the pressure l fill of the plates 20 to wind the screen. It will be further seen that I have provided means for preventing insects from entering between the window sash and screen, two different forms of shield or guard being disclosed in the drawings.

As described, above, the screening 16 is preferably of cloth fabric as this will more readily wind upon the roller than will wire screening and, of course, it will be understood that when cloth fabric is used it will necessarily have to be of a water proof construction. I do not desire to limit myself to any particular construction or form of screening, but in experimenting I have found that wire fabric will not tightly wind upon the roller but instead will have a tendency to spread out, thus forming a very bulky roll.

Having fully described my invention what I claim as new and desire to secure by Letters Patentis:

1. A mounting for a roller carried screen comprising an angle iron frame, a plate hingedly connected to the frame for engaging the longitudinal edges of the screening when the same is unwound from the roller,

and means carried by the plate and adapted to engage over the edge of the frame for holding the plate away from the screening.

2. A mounting for a roller carried screen comprising an angle iron frame, a plate hingedly connected to the frame for engaging the longitudinal edge of the screening when the same is unwound from the roller, and a catch pivotally connected to the plate and adapted to engage over the edge of the frame for holding the plate away from the screening.

A mounting for a roller carried screen comprising an angle iron frame, a plate hingedly connected to each side. of the frame, springs for normally holding the plates in engagement with the sides of the frame for clamping the screening therebetween, when unwound from the roller, and catches pivotally connected to the plates and adapted to engage over edges of the sides of the frame for holding them away from the screening.

In testimony whereof I hereunto affix my signature.

AUGUST A. GASSINGEB.
